Implementations

impl Variant

pub fn from_variant(vt: &VARIANT) -> WMIResult<Variant>

Create a Variant instance from a raw VARIANT.

Safety

This function is unsafe as it is the caller’s responsibility to ensure that the VARIANT is correctly initialized.

pub fn convert_into_cim_type( self, cim_type: CIMTYPE_ENUMERATION ) -> WMIResult<Self>

Convert the variant it to a specific type.

impl PartialEq for Variant

fn eq(&self, other: &Variant) -> bool
